SHR1701 Alone or in Combination With SHR2554 in Relapsed or Refractory Classical Hodgkin Lymphoma

An Open-Label Phase I/II Study of SHR1701 Alone or in Combination With SHR2554 in Relapsed or Refractory Classical Hodgkin Lymphoma

This is an open-label, phase I/II dose escalation and expansion trial. The primary objective of dose escalation phase I study is to evaluate the safety and feasibility of SHR1701 in patients with relapsed or refractory classical Hodgkin Lymphoma. The primary objective of open-label, randomized, phase II study is to assess the antitumor effect of SHR1701 alone or in combination with SHR2554 in patients with relapsed or refractory classical Hodgkin Lymphoma.

Study Overview

• Status: Recruiting
• Conditions: Relapsed or Refractory Hodgkin Lymphoma
• Intervention / Treatment: Drug: SHR-1701; Drug: SHR2554+ SHR1701

Detailed Description

In phase I study, patients received intravenous SHR1701 30-150 mg/kg every 3 weeks. Sequential patient groups received the following doses of SHR1701: 30 mg/kg, 60 mg/kg, 90 mg/kg, 120 mg/kg, or 150 mg/kg in a 3+3 design with the intention of determining the recommended dose for phase 2. Toxicities are graded according to the Common Terminology Criteria for Adverse Events, version 5.0.

In phase II expansion study, based on the recommended dose of SHR1701 from phase I study, patients are treated with SHR1701 alone if CR rate is satisfactory, or randomized to SHR1701 monotherapy group or SHR2554 plus SHR1701 combination group to assess the clinical efficacy of SHR2554 plus SHR1701 combination therapy.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Phase I : Adverse events	Incidence, nature, and severity of adverse events graded according to the NCI CTCAE v4.03.	Up to 90 days after the last dose of study drugs
Phase I/ II: Complete response rate (CRR)	CRR assess by investigators per the 2014 Lugano classification rate of subjects achieved complete response in all evaluable subjects	up to 36 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Phase II: Objective response rate (ORR)	The percentage of patients with CR or PR was determined according to the revised lymphoma efficacy evaluation criteria (Lugano 2014 criteria).	up to 36 months
Phase II: Progression-free survival (PFS)	Time from the date of first administration of the study drug to disease progression or death from any cause.	up to 36 months
Phase II: Overal survival	The median overall survival (OS) time is defined as the time from enrollment to the date of death.	up to 36 months
Phase II: Duration of response (DOR)	Time from the first recording of CR or PR evidence to disease progression or death from any cause which was determined according to the revised lymphoma efficacy evaluation criteria (Lugano 2014 criteria).	up to 36 months

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
Phase II: Biomarkers predictive of efficacy and toxicity	Biomarkers such as EZH2, PD-L1 and TGF-β from tumor tissue and peripheral blood will be assessed for their potential in predicting clinical efficacy and toxicity.	up to 36 months
